I don't think it's sheryl because they were hugging terms pa ni ynez when she celebrated her bday... so it must be gladys reyes and mane or baka si gladys lang kasi the term is BFF and not BFFS and "magsama sila" ang term na ginamit as opposed to a more accurate one pag 3 tao ang tinutukoy which is "magsama-sama sila" --- hahaha! at tlgng sinuri ang mensahe!?!!!!
